I agree. There is no major damage to the model as it stands, and nothing glaringly wrong. OK, so a touch of paint didn't go the way you wanted it to - an important step in building experience in modelling. You have paint, you have brushes, and you have the inclination - leave it a day or two, or a week or two, then come back to it, assess what you want to achieve, think about it and plan how you're going to go about it - don't rush into it. Then start some remedial work.
